Error 310

DESCRIPTION:

Some of the IENS subscripts in this FDA conflict with each other. For
example, one IENS may use the sequence number ?1 while another uses +1. This
would be illegal because the sequence number 1 is being used to represent two
different operations.

Consult your documentation for an explanation of the various conflicts
possible.

The IENS returned with this error happens to be one of the IENS values
in conflict.
